Hi,

after creating the standard RuleFlow example with Drools 5 in Eclipse,
adding a gateway with two (true) constraints leads to the following error
"org.drools.compiler.RuleFlowLoadError: Unable to load the rule flow. :
Exception class org.xml.sax.SAXParseException : <constraint> requires a
'toType' attribute". This seems to be a very basic serious problem.

Here is my RuleFlow file in which I only added one split node and a trivial
output action.

<connection from="2" to="3" />
<connection from="1" to="4" />
<connection from="4" to="5" />
<connection from="5" to="6" />
</connections>
</process>

Any ideas?

Thanks in advance

Marc
